Note 1. Consult SERDES manufacturer’s application information for biasing required for Tx outputs. Some serializer outputs
are internally biased and may not need external bias resistors.
Signal Detect
The C-1X-2500(C)-FDFB-SLC4 transceivers are equipped with LVTTL / LVPECL signal detect outputs. The standard LVTTL output eliminates
the need for a LVPECL to LVTTL level shifter in most in most applications.
